Writeup from MB 98:

En Naffatiyah        33°13.133’N, 10°50.067’E

Tunisia

Found: 20 Mar 2007

Classification: Ordinary chondrite (L6)

History: A single stone of 87.2 g was found south-east of Medenine near the small village of Neffatia (Naffatiyah) by an anonymous finder, who is Tunisian, and holds the main mass.

Petrography: (A. Bischoff, IfP). The hand specimen is very brown resulting from severe weathering in the desert. In thin section, the texture of En Naffatiyah is highly recrystallized and only a few relic chondrules are visible. This indicates a high metamorphic grade as does the homogeneous composition of olivine and pyroxene. Based on the mean olivine and low-Ca pyroxene compositions of Fa25.5 and Fs21, respectively, the rock is classified as an L-group ordinary chondrite. Based on the classification scheme of Stöffler et al. (1991) the rock is moderately shocked (S4) as indicated by mosaicism in olivine and the transformation of some plagioclase into maskelynite. Shock veins go throughout the sample. The weathering effects are inhomogeneous within the sample (W2-3).

Classification: En Naffatiyah is an L6, S4, W2-3, ordinary chondrite.

Specimens: A mass of 19 g and one thin section are on deposit at IfP. An anonymous collector holds the main mass.
